摘要(Abstract)

家庭智能网关是家居智能化的心脏,通过它实现系统信息的采集、信息输入、信息输出、集中控制、远程控制、联动控制等功能。现在路由器和电视盒子集成的技术已经实现。最近就曝光了一款跨界融合的智能无线产品骇客H3,它是集高清IPTV、私有云、智能家居、智能无线路由、多屏游戏等功能于一身,JCG将其定位为"智能家庭网关"。软件定义网络(Software Defined Network,SDN)是由美国斯坦福大学CLean State课题研究组提出的一种新型网络创新架构,是网络虚拟化的一种实现方式。其核心技术OpenFlow通过将网络设备的控制面与数据面分离开来,从而实现了网络流量的灵活控制,使网络作为管道变得更加智能,为核心网络及应用的创新提供了良好的平台。 中文名 软件定义网络 外文名 Software Defined Network 简 称 SDN 应用领域 计算机 类 别 Open SDN;;APISDN;堆叠SDN软件定义网络( SDN)是一种软件集中控制、网络开放的三层体系架构,如图(1)所示。应用层实现对网络业务的呈现和网络模型的抽象;控制层实现网络操作系统功能,集中管理网络资源;转发层实现分组交换功能。应用层与控制层之间的北向接口是网络开放的核心,控制层的产生实现了控制面与转发面的分离,是集中控制的基础。SDN最主要的特征就是数据转发和控制分离, 同时还具有网络虚拟化和开放接口
